Applications

Ochratoxin B is the non-chlorinated analogue of the much more extensively studied Ochratoxin A. It is co-produced by the same species of Aspergillus and Penicillium that are associated with food spoilage. Ochratoxin B has received little focused investigation. Its mode of action and its potential hazards might have been inferred from Ochratoxin-A.
